If the power dissipation remains high, the thermal shutdown 4.2 Overcurrent protection circuitry will again turn off the LDO, protecting it from catastrophic failure. The MCP1703 internal circuitry monitors the amount of current flowing through the P-Channel pass transistor. In the event of a short-circuit or excessive output current, the MCP1703 will turn off the P-Channel device for a short period, after which the LDO will attempt to restart. If the excessive current remains, the cycle will repeat itself.

MCP1703 5.0 FUNCTIONAL DESCRIPTION 5.2 Output The MCP1703 CMOS low dropout linear regulator is The maximum rated continuous output current for the intended for applications that need the lowest current MCP1703 is 250mA (VR ≥ 2.5V). For applications consumption while maintaining output voltage where VR < 2.5V, the maximum output current is regulation. The operating continuous load range of the 200mA. MCP1703 is from 0mA to 250mA (VR ≥ 2.5V). The A minimum output capacitance of 1.0µF is required for input operating voltage range is from 2.7V to 16.0V, small signal stability in applications that have up to making it capable of operating from two or more 250mA output current capability. The capacitor type alkaline cells or single and multiple Li-Ion cell batteries. can be ceramic, tantalum, or aluminum electrolytic. The esr range on the output capacitor can range from 0Ω to 5.1 Input 2.0Ω. The input of the MCP1703 is connected to the source The output capacitor range for ceramic capacitors is of the P-Channel PMOS pass transistor. As with all 1µF to 22µF. Higher output capacitance values may LDO circuits, a relatively low source impedance (10Ω) be used for tantalum and electrolytic capacitors. Higher is needed to prevent the input impedance from causing output capacitor values pull the pole of the LDO the LDO to become unstable. The size and type of the transfer function inward that results in higher phase capacitor needed depends heavily on the input source shifts which in turn cause a lower crossover frequency. type (battery, power supply) and the output current The circuit designer should verify the stability by range of the application. For most applications (up to applying line step and load step testing to their system 100mA), a 1µF ceramic capacitor will be sufficient to when using capacitance values greater than 22µF. ensure circuit stability. Larger values can be used to improve circuit AC performance. 5.3 Output Rise time When powering up the internal reference output, the typical output rise time of 1000µs is controlled to prevent overshoot of the output voltage. © 2009 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.
