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% maximum over the operating junction
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.

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.
