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 devices • Power supply for personal communication devices • Power supply for note PCs „ Packages Package Name SOT-89-3 SOT-89-5 6-Pin HSON(A) Package UP003-A UP005-A PD006-A Drawing Code Tape UP003-A UP005-A PD006-A Reel UP003-A UP005-A PD006-A Seiko Instruments Inc. 1 HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.3.0_01 S-1131 Series „ Block Diagrams (1) Without shutdown function (Package : SOT-89-3) *1 VIN VOUT Overcurrent protector www.DataSheet4U.com + − Reference voltage circuit VSS *1.
