The error amplifier output Aluminum-electrolytic and tantalum capacitors can be will adjust the amount of current that flows through the used on the LDO output as well.

The MCP1804 internal circuitry monitors the amount of current flowing through the P-Channel pass transistor. 4.5 Input Capacitor In the event that the load current reaches the current limiter level of 200mA (typical), the current limiter Low input source impedance is necessary for the LDO circuit will operate and the output voltage will drop. As output to operate properly. When operating from the output voltage drops, the internal current foldback batteries or in applications with long lead length circuit will further reduce the output voltage causing the (>10inches) between the input source and the LDO, output current to decrease. When the output is shorted, some input capacitance is recommended. A minimum a typical output current of 50mA flows. of 0.1µF to 1.0µF is recommended for most applications. 4.3 Shutdown For applications that have output step load The SHDN input is used to turn the LDO output voltage requirements, the input capacitance of the LDO is very on and off. When the SHDN input is at a logic-high important. The input capacitance provides the LDO level, the LDO output voltage is enabled. When the with a good local low-impedance source to pull the SHDN input is pulled to a logic-low level, the LDO transient currents from in order to respond quickly to output voltage is disabled and the LDO enters a low the output load step.

Therefore The capacitor should be placed as close to the input of the SHDN pin must be pulled either high or low to the LDO as is practical. Larger input capacitors will also prevent the device from becoming unstable. The help reduce any high-frequency noise on the input and internal device current will increase when the device is output of the LDO and reduce the effects of any operational and current flows through the pull-up or inductance that exists between the input source pull-down resistor to the SHDN pin internal logic.

MCP1804 5.0 FUNCTIONAL DESCRIPTION The MCP1804 CMOS linear regulator is intended for applications that need low current consumption while maintaining output voltage regulation. The operating continuous load of the MCP1804 ranges from 0mA to 150mA. The input operating voltage ranges from 2.0V to 28.0V, making it capable of operating from a single 12V battery or single and multiple Li-Ion cell batteries. 5.1 Input The input of the MCP1804 is connected to the source of the P-Channel PMOS pass transistor. As with all LDO circuits, a relatively low source impedance (<10) is needed to prevent the input impedance from causing the LDO to become unstable. The size and type of the capacitor needed depend heavily on the input source type (battery, power supply) and the output current range of the application. For most applications, a 0.1µF ceramic capacitor will be sufficient to ensure circuit stability. Larger values can be used to improve circuit AC performance. 5.2 Output The maximum rated continuous output current for the MCP1804 is 150mA. A minimum output capacitance of 0.1µF to 1.0µF is required for small signal stability in applications that have up to 150mA output current capability. The capacitor type can be ceramic, tantalum or aluminum electrolytic.  2009-2013 Microchip Technology Inc. DS20002200D-page 19

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.
