MCP1703A  
250 mA, 16V, Low Quiescent Current LDO Regulator  
Features:  
Description:  
• Reduced Ground Current During Dropout  
• Faster Startup Time  
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.  
• 2.0 µA Typical Quiescent Current  
• Input Operating Voltage Range: 2.7V to16.0V  
• 250 mA Output Current for Output Voltages 2.5V  
• 200 mA Output Current for Output Voltages < 2.5V  
• Low Dropout Voltage, 625 mV Typical @ 250 mA  
for VR = 2.8V  
The MCP1703A is capable of delivering 250 mA with  
only 625 mV (typical) of input to output voltage  
differential (VOUT = 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.  
• 0.4% Typical Output Voltage Tolerance  
• Standard Output Voltage Options:  
- 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V,  
5.0V  
• Output Voltage Range: 1.2V to 5.5V in 0.1V  
Increments (50 mV increments available upon  
request)  
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.  
• A/D Friendly Voltage Options: 2.05V, 3.07V, 4.1V  
• Stable with 1.0 µF to 22 µF Ceramic Output  
Capacitance  
• Short-Circuit Protection  
• Overtemperature Protection  
Applications:  
• Battery-Powered Devices  
• Battery-Powered Alarm Circuits  
• Smoke Detectors
