SBAS221H – DECEMBER 2001 – REVISED OCTOBER 2015 REG710xx Buck-Boost Charge Pump with up to 60-mA Output Current
1 Features 3 Description The REG710 family of devices are switched capacitor
voltage converters that generate regulated, low-ripple
output voltage from an unregulated input voltage. A
wide input supply voltage from 1.8 V to 5.5 V makes
the REG710 family of devices ideal for a variety of
battery sources, such as single-cell Li-Ion, or 2-cell
and 3-cell nickel-based or alkaline-based chemistries. 1 Wide Input Voltage Range: 1.8 V to 5.5 V
