MCP1754/MCP1754S

150 mA, 16V, High Performance LDO

Description

Features

• High PSRR: >70 dB @ 1 kHz typical

The MCP1754/MCP1754S is a family of CMOS low

dropout (LDO) voltage regulators that can deliver up to

150 mA of current while consuming only 56.0 µA of

quiescent current (typical). The input operating range is

specified from 3.6V to 16.0V, making it an ideal choice

for four to six primary cell battery-powered applications,

12V mobile applications and one- to three-cell Li-Ion-

powered applications.

• 56.0 µA Typical Quiescent Current

• Input Operating Voltage Range: 3.6V to16.0V

• 150 mA Output Current for All Output Voltages

• Low Drop Out Voltage, 300 mV Typical @ 150 mA

• 0.4% Typical Output Voltage Tolerance

• Standard Output Voltage Options (1.8V, 2.5V,

2.8V, 3.0V, 3.3V, 4.0V, 5.0V)

The MCP1754/MCP1754S is capable of delivering

150 mA with only 300 mV (typical) of input to output

voltage differential. The output voltage tolerance of the

MCP1754/MCP1754S is typically ±0.4% at +25°C and

±2.0% maximum over the operating junction

temperature range of -40°C to +125°C. Line regulation

is ±0.01% typical at +25°C.

• Output Voltage Range 1.8V to 5.5V in 0.1V

Increments (tighter increments also possible per

design)

• Output Voltage Tolerances of ±2.0% Over Entire

Temperature Range

• Stable with Minimum 1.0 µF Output Capacitance

• Power Good Output

Output voltages available for the MCP1754/MCP1754S

range from 1.8V to 5.5V. The LDO output is stable when

using only 1 µF of output capacitance. Ceramic,

tantalum or aluminum electrolytic capacitors may all be

used for input and output. Overcurrent limit and

overtemperature shutdown provide a robust solution for

any application.

• Shutdown Input

• True Current Foldback Protection

• Short-Circuit Protection

• Overtemperature Protection

Applications

The MCP1754/MCP1754S family introduces a true

current foldback feature. When the load impedance

decreases beyond the MCP1754/MCP1754S load

rating, the output current and voltage will gracefully

foldback towards 30 mA at about 0V output. When the

load impedance decreases and returns to the rated

load, the MCP1754/MCP1754S will follow the same

foldback curve as the device comes out of current

foldback.

• Battery-powered Devices

• Battery-powered Alarm Circuits

• Smoke Detectors

• CO²Detectors

• Pagers and Cellular Phones

• Smart Battery Packs

• PDAs

Package options for the MCP1754S include the SOT-

23A, SOT-89-3, SOT-223-3 and 2x3 DFN-8.

• Digital Cameras

• Microcontroller Power

• Consumer Products

• Battery-powered Data Loggers

Package options for the MCP1754 include the SOT-23-

5, SOT-223-5, and 2x3 DFN-8.
