MCP1801

150 mA, High PSRR, Low Quiescent Current LDO

Features

Description

• 150 mA Maximum Output Current

The MCP1801 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 150 mA of

current while consuming only 25 µA of quiescent

current (typical). The input operating range is specified

from 2.0V to 10.0V, making it an ideal choice for two to

six primary cell battery-powered applications, 9V alka-

line and one or two cell Li-Ion-powered applications.

• Low Drop Out Voltage, 200 mV typical @ 100 mA

• 25 µA Typical Quiescent Current

• 0.01 µA Typical Shutdown Current

• Input Operating Voltage Range: 2.0V to10.0V

• Standard Output Voltage Options:

0.9V, 1.2V, 1.8V, 2.5V, 3.0V, 3.3V, 5.0V, 6.0V

The MCP1801 is capable of delivering 100 mA with

only 200 mV (typical) of input to output voltage differen-

tial (V_OUT= 3.3V). The output voltage tolerance of the

MCP1801 at +25°C is typically ±0.4% with a maximum

of ±2%. Line regulation is ±0.01% typical at +25°C.

• Output voltage accuracy:

- ±2% (V_R> 1.5V), ±30 mV (V_R≤ 1.5V)

• Stable with Ceramic output capacitors

• Current Limit Protection

The LDO output is stable with a minimum of 1 µF of

output capacitance. Ceramic, tantalum or aluminum

electrolytic capacitors can all be used for input and

output. Overcurrent limit with current foldback provides

short-circuit protection. A shutdown (SHDN) function

allows the output to be enabled or disabled. When

disabled, the MCP1801 draws only 0.01 µA of current

(typical).

• Shutdown pin

• High PSRR: 70 dB typical @ 10 kHz
