S-1131

Rev.3.0_01 HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1131 Series www.DataSheet4U.com The S-1131 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life, and small SOT-89-3, SOT-89-5 and 6-Pin HSON(A) packages realize high-density mounting. „ Features Output voltage: High-accuracy output voltage: Low dropout voltage: Low current consumption: High peak current capability: Built-in ON/OFF circuit: High ripple rejection: Built-in overcurrent protector: Small package: Lead-free products 1.5 V to 5.5 V, selectable in 0.1 V steps. ±1.0% 250 mV typ. (3.0 V output product, IOUT = 100 mA) During operation: 35 µA typ., 65 µA max. During shutdown: 0.1 µA typ., 1.0 µA max. 300 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1 Ensures long battery life. 70 dB typ. (at 1.0 kHz) Overcurrent of output transistor can be restricted. SOT-89-3, SOT-89-5, 6-Pin HSON(A) *1. Attention should be paid to the power dissipation of the package when the output current is large. „ Applications Power supply for DVD and CD-ROM drives Power supply for battery-powered dev...
