SUPER-LOW OUTPUT LOW DROPOUT CMOS VOLTAGE REGULATOR
S-11L10 Series
S-11L10 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low output voltage, the high-accuracy output voltage and the low current consumption (150 mA output current). A 1.0 µF small ceramic capacitor can be used. It operates with low current consumption of 9 µA typ. The overcurrent protection circuit prevents the load current from exceeding the capacitance of output transistor. The power-off circuit ensures longer battery life. Various capacitors, also small ceramic capacitors, can be used for this IC more than for the conventional regulator ICs which have CMOS technology. Furthermore a small SOT-23-5 and SNT-6A(H) packages realize high-density mounting.
Features
• Low output voltage: • Low input voltage: • Low equivalent series resistance capacitor : • High-accuracy output voltage: • Low dropout voltage: • Low current consumption: 0.8 V to 3.3 V, selectable in 0.05 V step. 1.2 V to 3.65 V Ceramic capacitor of 1.0 µF or more can be used as the I/O capacitor. ±1.0% (0.8 V to 1.45 V output product : ±15 mV) 210 mV typ. (products having the output of 1.5 V, IOUT = 100 mA) During operation: 9.0 µA typ., 16 µA max. During power-off: 0.1 µA typ., 0.9 µA max. Possible to output 150 mA (at VIN ≥ VOUT(S) + 1.0 V)*1 60 dB typ. (at 1.0 kHz, VOUT = 1.25 V) limits overcurrent of output transistor Ensures long battery life.
• Output current: • Ripple rejection: • Built-in overcurrent protection circuit: • Built-in power-off circuit: • Discharge shunt function www.DataSheet4U.com • Selectable constant current source pull-down • Small package: SOT-23-5, SNT-6A(H) • Lead-free product
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
• Power supply for battery-powered devices • Power supply for mobile phones • Power supply for portable equipment
