Description:
The MCP1703A is an improved version of the
MCP1703 low dropout (LDO) voltage regulator that can
deliver up to 250 mA of current while consuming only
2.0 µA of quiescent current (typical). The input
operating range is specified from 2.7V to 16.0V, making
it an ideal choice for two to six primary cell battery-
powered applications, 9V alkaline and one or two cell
Li-Ion-powered applications.
The MCP1703A is capable of delivering 250 mA with
only 625 mV (typical) of input to output voltage
differential (V
OUT
= 2.8V). The output voltage tolerance
of the MCP1703A is typically ±0.4% at +25°C and ±3%
maximum over the operating junction temperature
range of -40°C to +125°C. Line regulation is ±0.1%
typical at +25°C.
Output voltages available for the MCP1703A range
from 1.2V to 5.5V. The LDO output is stable when using
only 1 µF of output capacitance. Ceramic, tantalum, or
aluminum electrolytic capacitors can all be used for
input and output. Overcurrent limit and overtemperature
shutdown provide a robust solution for any application.
Package options include the SOT-223-3, SOT-23A,
2x3 DFN-8, and SOT-89-3.
