The document describes the features and characteristics of the UR132 linear integrated circuit produced by UNISONIC TECHNOLOGIES CO., LTD. The circuit is a 200mA fixed output voltage low dropout linear regulator, with a wide range of available output voltage and excellent load regulation, fast transient response, and current-limiting and thermal-limiting protection.
The UR132 linear integrated circuit provides a fixed 200 mA output with low dropout voltage, supporting input voltages up to 12 V. It features tight load regulation, fast transient response, and built‑in current‑limiting and thermal‑limiting for protection.
Ordering information includes several part numbers for SOT‑23 and SOT‑25 packages, and the typical application circuit recommends a 10 µF (or larger) capacitor between VOUT and GND plus an additional 1 µF (or larger) capacitor between VIN and GND for stability.
| Output current | 200 mA |
|---|---|
| Input voltage range | 0 V to 12 V |
| Dropout voltage | 1.5 V (typical) |
| Standby current | 3.0 mA (Vin=9 V) |
| Power dissipation | 300 mW |
| Package types | SOT‑23, SOT‑25 |
The device can operate with an input voltage up to 12 V.
It guarantees a fixed output current of 200 mA.
A 10 µF (or larger) capacitor between VOUT and GND and another 1 µF (or larger) capacitor between VIN and GND are recommended.
