SUPER-SMALL PACKAGE 2-CIRCUIT BUILT-IN DELAY FUNCTION HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.1.1_00
The S-13D1 Series, developed by using the CMOS technology, is a 2-channel positive voltage regulator IC which has low dropout voltage, high accuracy output voltage and low current consumption. A 0.22 μF small ceramic capacitor can be used, and the S-13D1 Series includes a load current protection circuit that prevents the output current from exceeding the current capacitance of the output transistor and a thermal shutdown circuit that prevents damage due to overheating. Also, C / F type in the S-13D1 Series has a built-in delay function that sets the difference of rising time in a channel.
Features
1.0 V to 3.6 V, selectable in 0.05 V step A ceramic capacitor of 0.22 μF or more can be used for the output capacitor. • Input voltage: 1.5 V to 5.5 V • High-accuracy output voltage: ±1.0% (1.0 V to 1.45 V output product :±15 mV) • Dropout voltage: 80 mV typ. (2.8 V output product, IOUT = 100 mA) • Low current consumption: During operation: 39 μA typ., 58 μA max. (per circuit) During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 150 mA (at VIN ≥ VOUT(S) + 1.0 V)*1 (per circuit) • High output current: • High ripple rejection: 70 dB typ. (3.6 V output product, at f = 1.0 kHz) • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in thermal shutdown circuit: Prevents damage caused by heat. • Built-in ON / OFF circuit: Ensures long battery life. • Constant current source pull-down is selectable. • Discharge shunt function is selectable. • Delay function is selectable. • Operation temperature range: Ta = −40°C to +85°C • Lead-free (Sn 100%), halogen-free*2
