Description
RT9193-15GB is a fixed-output low-dropout (LDO) regulator from Richtek. The “-15” means 1.5 V fixed output, and “GB” denotes a Pb-free/Green package variant.
Key points:
- Output: fixed 1.5 V
- Output current: up to about 150 mA
- Input range: typically up to about 5.5 V
- Characteristics: low dropout, low quiescent current, fast transient response
- Protections: current limit and thermal/shutdown protection
- Package: small Pb-free option (GB)
Typical uses:
- Battery-powered devices, microcontrollers, and sensors requiring a stable 1.5 V rail
Quick use notes:
- Input to Vin, ground to GND, output to Vout with a nearby decoupling capacitor.
