Microchip | MCP1700T-1502E/MB

The MCP1700 series of CMOS low dropout positive voltage regulator which can source up to 250 mA of current with an extremely low input-output voltage differential of 178 mV at 250 mA. The low dropout voltage combined with the low current consumption of only 1.6 µA makes this part ideal for battery operation.

The low voltage differential (dropout voltage) extends battery operating lifetime. The MCP1700 is stable with 1.0 µF ceramic output capacitor. It also permits high currents in small packages when operated with minimum VIN – VOUT differentials. The circuit also incorporates short-circuit protection & over temperature protection to ensure maximum reliability. 

Features:

• Extremely Low Operating Current for Longer Battery Life (1.6 uA typical) 
• Very Low Dropout Voltage (178 mV at full load) 
• Rated 250 mA Output Current 
• High Output Voltage Accuracy (±0.4% typical) 
• Over-Current and Over-Temperature Protection
