- Low Dropout (LDO): Operates efficiently with input voltages as low as 3.8V.
- 100mA Output Current: Supports moderate power applications.
- Low Quiescent Current: Consumes only 4µA (typical) in standby mode.
- SOT-89 Package: Compact footprint for PCB space optimization.
Technical Specifications:
- Input Voltage Range: 3.8V to 12V
- Output Voltage: 3.3V ±2%
- Maximum Output Current: 100mA
- Dropout Voltage: 100mV (typical) at 50mA load
- Operating Temperature: –40°C to +85°C
Mechanical Specifications:
- Package Type: SOT-89 (surface-mount)
- Pin Material: Lead-free, RoHS-compliant
- Thermal Resistance: 160°C/W (junction-to-ambient)
Dimensions:
- Package Size: 4.5mm × 4.0mm × 1.5mm
- Lead Spacing: 1.5mm (between pins)
Pinout and Wiring:
- Pin 1 (Input): Connect to unregulated DC supply (3.8V–12V).
- Pin 2 (Ground): Common ground for input/output.
- Pin 3 (Output): Delivers regulated 3.3V to the load.
- Add a 1µF–10µF ceramic capacitor at the input/output for stability.
