TPS7A4701RGWR General Description

The TPS7A4701RGWR is an LDO voltage regulator IC designed to deliver a precise and stable output voltage, even when the input voltage may vary or have noise. LDO regulators are commonly used to power sensitive analog and digital circuits that require a clean and stable power supply.

Key Features

Input Voltage Range: +3 V to +36 V
Output Voltage Noise: 4 µV_RMS (10 Hz, 100 kHz)
Power-Supply Ripple Rejection:
- 82 dB (100 Hz)
- > 55 dB (10 Hz, 10 MHz)
Two Output Voltage Modes:
- ANY-OUT™ Version (User-Programmable Output via PCB Layout):
  - No External Feedback Resistors or Feed-Forward Capacitors Required
  - Output Voltage Range: +1.4 V to +20.5 V
- Adjustable Version (TPS7A4701 only):
  - Output Voltage Range: +1.4 V to +34 V
Output Current: 1 A
Dropout Voltage: 307 mV at 1 A
CMOS Logic Level-Compatible Enable Pin
Built-In Fixed Current Limit and Thermal Shutdown
Available in High-Performance Thermal Package: 5-mm × 5-mm QFN
Operating Temperature Range: –40°C to 125°C
