Présentation

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.

Equivalent

Equivalent 1.5V fixed LDO regulators with similar current (about 150–250 mA) and footprints:
- Torex XC6206P152MR (SOT-23-3)
- Microchip MCP1700-1.5 (SOT-23-3)
- Analog Devices ADP170AUJZ-1.5 (SOT-23-3)
Other vendors offer 1.5V fixed LDOs in similar packages; verify input range, dropout, and footprint for your design.

Features

RT9193-15GB is a fixed 1.5V low-dropout regulator from RichTek. Key features:
- Fixed output: 1.5 V
- Output current: up to about 150 mA
- Low dropout: tight regulation at light/heavy loads
- Very low quiescent current (typical tens of µA)
- Enable pin for easy shutdown/control
- Protective features: thermal shutdown and current limit
- Stable with ceramic output capacitors (1 µF or larger; buffer ESR within range)
- Input voltage range: up to about 5.5 V
- Low noise for sensitive applications
- Small package: SOT-23-5 with lead-free (-GB) version
Note: exact electricals (dropout, Iq, ESR ranges) vary slightly by lot; consult the datasheet for precise numbers and capacitor recommendations.

Pinout

- Pin count: 5 pins (SOT-23-5)
- Function: 150 mA fixed-output low-dropout regulator with 1.5 V output. Pin functions: VIN (input), VOUT (regulated 1.5 V), GND (ground), EN (enable), and one NC (no connect) pin on this fixed-version variant.

Manufacturer

- Manufacturer: Richtek Technology Corp. (Richtek)
- What kind of company: A Taiwan-based fabless semiconductor company that designs and markets analog/mixed-signal power management ICs, including DC-DC converters, LDOs, and other PMICs for portable electronics.

Application
