HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION
S-1701 Series
The S-1701 Series, developed based on CMOS technology, is a voltage regulator with a reset function and integrates a highaccuracy voltage detector with on-chip delay circuit and a positive voltage regulator with a low dropout voltage and high output voltage on one chip. The S-1701 Series is available in many types according to the selection of the voltage detector block of the voltage detector, including a SENSE pin input product. A built-in low on-resistance transistor provides a low dropout voltage and large output current. Small ceramic capacitors are available and an external capacitor for delay is needless. Small SOT-23-5 and SOT-89-5 packages realize high-density mounting.
Features
Regulator block Output voltage: High-accuracy output voltage: High peak current capability: Built-in ON/OFF circuit: 1.5 to 5.0 V, selectable in 0.1 V steps. ±1.0% 400 mA output is possible (at VIN ≥ VOUT(S) + 2.0 V)*1 Ensures long battery life. During power-off: 0.1 A typ., 1.0 A max. Low ESR capacitor can be used: A ceramic capacitor of 1.0 F or more can be used for the output capacitor. 70 dB typ. (at 1.0 kHz) High ripple rejection: Overcurrent of output transistor can be restricted. Built-in overcurrent protector: 2.0 to 6.5 V Operating voltage range:
Detector block 1.5 to 5.5 V, selectable in 0.1 V steps. Output voltage: High-accuracy output voltage: ±1.0% Nch open-drain ……
