Monolithic IC MM166
Outline
F
This IC is a small, stable power supply with output voltage precision of ±2% (when I
O
= 500mA), maximum
output current of 1000mA, and I/O voltage difference of 0.2V typ. at 500mA.
Output noise reduction and output ON/OFF control pins are provided, making it ideal for portable equipment.
(HSOP-8)
