MCP1755/1755S 3.5 Unregulated Input Voltage (V ) IN Connect V to the input unregulated source voltage. IN Like all low dropout linear regulators, low source impedance is necessary for the stable operation of the LDO. The amount of capacitance required to ensure low source impedance will depend on the proximity of the input source capacitors or battery type. For most applications, 1µF of capacitance will ensure stable operation of the LDO circuit. The input capacitor should have a capacitance value equal to or larger than the output capacitor for performance applications. The input capacitor will supply the load current during transients and improve performance. For applications that have load currents below 10mA, the input capacitance requirement can be lowered. The type of capacitor used may be ceramic, tantalum or aluminum electrolytic. The low ESR characteristics of the ceramic will yield better noise and PSRR performance at high frequency. 3.6 Exposed Pad (EP) Some of the packages have an exposed metal pad on the bottom of the package. The exposed metal pad gives the device better thermal characteristics by providing a good thermal path to either the PCB or heatsink to remove heat from the device.

MCP1755/1755S 4.5 Power Good Output (PWRGD) The open drain PWRGD output is used to indicate when the output voltage of the LDO is within 92% V IN T (typical value, see Section1.0 “Electrical DELAY_SHDN Characteristics” for Minimum and Maximum specifications) of its nominal regulation value. As the output voltage of the LDO rises, the open-drain PWRGD output will actively be held low until the output SHDN TPG voltage has exceeded the power good threshold plus the hysteresis value. Once this threshold has been exceeded, the power good time delay is started (shown as T in the AC/DC Characteristics table). The PG power good time delay is fixed at 100µs (typical). After VOUT the time delay period, the PWRGD open-drain output becomes inactive and may be pulled high by an external pullup resistor, indicating that the output voltage is stable and within regulation limits. The power PWRGD good output is typically pulled up to V or V . Pulling IN OUT the signal up to V conserves power during OUT Shutdown mode. C =1.0µF LOAD If the output voltage of the LDO falls below the power good threshold, the power good output will transition FIGURE 4-3: Power Good Timing from low.

If the shutdown input is pulled low for more than 400ns, the LDO will enter Shutdown mode. This The power good output is an open-drain output that can small bit of filtering helps to reject any system noise be pulled up to any voltage that is equal to or less than spikes on the shutdown input signal. the LDO input voltage. This output is capable of sinking a minimum of 5mA (V <0.45V). On the rising edge of the SHDN input, the shutdown PWRGD circuitry has a 135µs delay before allowing the LDO output to turn on. This delay helps to reject any false turn-on signals or noise on the SHDN input signal. After V PWRGD_TH the 135µs delay, the LDO output enters its soft-start period as it rises from 0V to its final regulation value. If V OUT the SHDN input signal is pulled low during the 135µs T PG delay period, the timer will be reset and the delay time will start over again on the next rising edge of the VOH SHDN input. The total time from the SHDN input going TV DET_PWRGD high (turn-on) to the LDO output being in regulation is typically 235µs. See Figure4-4 for a timing diagram of PWRGD the SHDN input.

MCP1755/1755S 4.8 Overtemperature Protection T DELAY_SHDN The MCP1755/1755S LDO has temperature-sensing 400ns (typical) circuitry to prevent the junction temperature from 135µs exceeding approximately +150°C. If the LDO junction temperature does reach +150°C, the LDO output will SHDN be turned off until the junction temperature cools to approximately +140°C, at which point the LDO output will automatically resume normal operation. If the internal power dissipation continues to be excessive, the device will again shut off. The junction temperature V of the die is a function of power dissipation, ambient OUT temperature and package thermal resistance. See Section5.0 “Application Circuits and Issues” for CLOAD = 1.0 µF more information on LDO power dissipation and junction temperature. FIGURE 4-4: Shutdown Input Timing Diagram. 4.7 Dropout Voltage and Undervoltage Lockout Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below the nominal value that was measured with a V +1.0V differential applied. The MCP1755/1755S R LDO has a very low dropout voltage specification of 300mV (typical) at 300mA of output current. See Section1.0 “Electrical Characteristics” for maximum dropout voltage specifications. The MCP1755/1755S LDO operates across an input voltage range of 3.6V to 16.0V and incorporates input undervoltage lockout (UVLO) circuitry that keeps the LDO output voltage off until the input voltage reaches a minimum of 3.00V (typical) on the rising edge of the input voltage. As the input voltage falls, the LDO output will remain on until the input voltage level reaches 2.70V (typical). For high-current applications, voltage drops across the PCB traces must be taken into account. The trace resistances can cause significant voltage drops between the input voltage source and the LDO. For applications with input voltages near 3.0V, these PCB trace voltage drops can sometimes lower the input voltage enough to trigger a shutdown due to undervoltage lockout.  2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
