S-1172B25-U5T1G - Brand New ABLIC IC Chips
-
Description
The S-1172B25-U5T1G is a positive voltage regulator developed based on CMOS technology. It features a super low dropout voltage, high output voltage accuracy, and low current consumption. The regulator provides a small dropout voltage and large output current due to the built-in transistor with low on-resistance. It also includes an overcurrent protector to prevent load current from exceeding the output transistor's capacitance. The thermal shutdown circuit protects against heat damage, and the rush current control circuit limits excessive rush current during start-up.
Specifications and features
- Output voltage: 1.0 to 5.0 V, selectable in 0.05 V increments
- Low equivalent series resistance capacitor: Ceramic capacitor of 4.7 µF or more can be used as the I/O capacitor
- Input voltage: 1.5 to 5.5 V
- High-accuracy output voltage: ±1.0% (±15 mV for 1.0 to 1.45 V output products)
- Low dropout voltage: 70 mV typ. (3.0 V output product, at IOUT = 300 mA)
- Low current consumption: During operation: 70 µA typ., 90 µA max. (3.0 V output product); During shutdown: 0.1 µA typ., 1.0 µA max.
