HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
S-1132 Series
The S-1132 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption (300 mA output current) developed based on CMOS technology. A 0.1 µF small ceramic capacitor can be used. It operates with low current consumption of 20 µA typ. A built-in Output current protector prevents the load current from exceeding the current capacitance of the output transistor. Compared with the conventional 300 mA output current CMOS voltage regulators, high-density mounting is realized by using the super-small SNT-6A(H) package and a 0.1µF small ceramic capacitor. Also, the low current consumption makes the S-1132 series ideal for mobile devices.
Features
• Output voltage: • Low ESR capacitor can be used: • Wide input voltage range: • High-accuracy output voltage: • Low dropout voltage: • Low current consumption: • Output current: • High ripple rejection: • Built-in overcurrent protector: • Built-in ON/OFF circuit: • Small package: 1.5 V to 5.5 V, selectable in 0.1 V steps. A ceramic capacitor of 0.1 µF or more can be used for the output capacitor. 2.0 V to 6.5 V ±1.0% DataSheet4U.com 130 mV typ. (3.0 V output product, IOUT = 100 mA) During operation: 20 µA typ., 40 µA max. During shutdown: 0.01 µA typ., 1.0 µA max. 300 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1 70 dB typ. (at 1.0 kHz) Overcurrent of output transistor can be restricted. Ensures long battery life. SOT-23-5, SOT-89-5, SNT-6A(H)
