MCP1754/MCP1754S

Description

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.

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%

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

is ±0.01% typical at +25°C.

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.

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.

Package options for the MCP1754S include the SOT-

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

Package options for the MCP1754 include the SOT-23-

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