S-1165

S-1165 Series www.sii-ic.com © Seiko Instruments Inc., 2002-2015 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.4.1_00 The S-1165 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, 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 protection circuit prevents the load current from exceeding the current capacity of the output transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realizes high-density mounting.  Features Output voltage: Output voltage accuracy: Dropout voltage: Current consumption: Output current: Ripple rejection: Built-in overcurrent protection circuit: Built-in ON/OFF circuit: Operation temperature range: Lead-free, Sn 100%, halogen-free*2 1.5 V to 5.5 V, selectable in 0.1 V step ±1.0% 140 mV typ. (3.0 V output product, IOUT = 200 mA) During operation: 35 μA typ., 65 μA max. During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 200 mA (VIN ≥ VOUT(S) + 1.0 V)*1 70 dB typ. (f = 1.0 kHz) Limits overcurrent of output transistor. Ensures long battery life. Ta = −40°C to +85°C *1. Attention should be paid to the power dissipation of the package when the output current is large. *2.
