MCP1804

150 mA, 28V LDO Regulator With Shutdown

Features

Description

• 150 mA Output Current

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.

• Low Drop Out Voltage, 260 mV typical @ 20 mA,

V_R= 3.3V

• 50 µA Typical Quiescent Current

• 0.01 µA Typical Shutdown Current

• Input Operating Voltage Range: 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.

• Standard Output Voltage Options

(1.8V, 2.5V, 3.0V, 3.3V, 5.0V, 10.0V, 12.0V)

• Output Voltage Accuracy: ±2%

• Output voltages from 1.8V to 18.0V in 0.1V

increments are available upon request

The LDO input and output is 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).

• Stable with Ceramic output capacitors

• Current Limit Protection With Current Foldback

• Shutdown pin

• High PSRR: 50 dB typical @ 1 kHz
