Description:

The MCP1804 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 150 mA of

current while consuming only 50 µA of quiescent

current (typical, 1.8V  V

OUT

 5.0V). The input

operating range is specified from 2.0V to 28.0V.

The MCP1804 is capable of delivering 100 mA with

only 1300 mV (typical) of input to output voltage

differential (V

OUT

= 3.3V). The output voltage tolerance

of the MCP1804 at +25°C is a maximum of ±2%. Line

regulation is ±0.15% typical at +25°C.

The LDO input and output are stable with 0.1 µF of

input and output capacitance. Ceramic, tantalum or

aluminum electrolytic capacitors can all be used for

input and output. Overcurrent limit with current foldback

to 40 mA (typical) provides short circuit protection.

A shutdown (SHDN

) function allows the output to be

enabled or disabled. When disabled, the MCP1804

draws only 0.01 µA of current (typical).

Package options include the 3-lead SOT-89, 3-lead

SOT-223, 5-lead SOT-23 and 5-lead SOT-89.

MCP1804 4.0 DETAILED DESCRIPTION 4.1 Output Regulation A portion of the LDO output voltage is fed back to the internal error amplifier and compared with the precision internal bandgap reference. The error amplifier output will adjust the amount of current that flows through the P-Channel pass transistor, thus regulating the output voltage to the desired value.
