150 mA, 28V LDO Regulator With Shutdown

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

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

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 is stable with 0.1 µF of input

and

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 SOT-23-5 (SOT-25), SOT-

89-3, SOT-89-5, and SOT-223-3.
