1 / 70 page Rev.2.4_00 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION S-1701 Series Seiko Instruments Inc. 1 The S-1701 Series, developed based on CMOS technology, is a voltage regulator with a reset function and integrates a high- accuracy 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: 1.5 to 5.0 V, selectable in 0.1 V steps. • High-accuracy output voltage: ±1.0% • High peak current capability: 400 mA output is possible (at VIN ≥ VOUT(S) + 2.0 V) *1 • Built-in ON/OFF circuit: Ensures long battery life. During power-off: 0.1 µA typ., 1.0 µA max. • Low ESR capacitor can be used: A ceramic capacitor of 1.0 µF or more can be used for the output capacitor. • High ripple rejection: 70 dB typ. (at 1.0 kHz) • Built-in overcurrent protector: Overcurrent of output transistor can be restricted. • Operating voltage range: 2.0 to 6.5 V Detector block • Output voltage: 1.5 to 5.5 V, selectable in 0.1 V steps. • High-accuracy output voltage: ±1.0% • Output mode: Nch open-drain active low output • No need of an external capacitor for delay • Three delay time settings: No delay (60 µs), 50 ms, 100 ms • Operating voltage range: 0.8 to 6.5 V Whole regulator • Low current consumption During operation: 85 µA typ. • Small package: SOT-23-5, SOT-89-5 • Lead-free products *1. Attention should be paid to the power dissipation of the package when the output current is large. Applications • Power supply and reset circuit for battery-powered devices • Power supply for personal communication devices • Power supply for home appliances Packages Drawing Code Package Name Package Tape Reel SOT-23-5 MP005-A MP005-A MP005-A SOT-89-5 UP005-A UP005-A UP005-A |
