Outline
This IC is a small, stable power supply with output voltage precision of ±2% (when IO = 250mA), maximum
output current of 500mA, and I/O voltage difference of 0.3V typ. at 250mA.
Output noise reduction and output ON/OFF control pins are provided, making it ideal for portable equipment.
Features
1. No-load current consumption
2. I/O voltage difference
3. Ripple rejection rate
4. Output current
5. Output noise voltage
6. Output voltage rank
7. Output ON/OFF control
