Description
The REG7 10 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-lon, or 2-cell
and 3-cell nickel-based or alkaline-based chemistries.
The input voltage may vary above and below the
output voltage and the output remains in regulation.
The device works as step-up or step-down converters
without the need of an inductor, providing low EMI
DC-DC conversion. The high switching frequency
allows the use of small surface-mount capacitors,
saving board space and reducing cost. The REG710
device is thermally protected and
current limited,
protecting the load and the regulator during fault
conditions. Typical ground pin current (quiescent
current) is 65 jA with no load, and less than 1 μA in
shutdown mode.

Feature Description
8.3.1 Shutdown Mode
The EN pin enables the IC when pulled high and places it into energy-saving shutdown mode when pulled low.
When in shutdown mode, the output is disconnected from the input and the quiescent current is reduced to 0.01
μA typical. This shutdown mode functionality is only valid when VIN is above the minimum recommended
operating voltage. The EN pin cannot be left floating and must be actively terminated either high or low.
Protection
The regulator includes thermal shutdown circuitry protecting the device from damage caused by overload
conditions. The thermal protection circuitry disables the. output when the junction temperature reaches
approximately 160°C, allowing the device to cool. When the junction temperature cools to approximately 140°C,
the output circuitry is automatically reenabled. Continuously operating the regulator into thermal shutdown can
degrade reliability. The regulator also provides current limit to protect itself and the load.
Device Functional Modes
Peak Current Reduction
In normal operation, the charging of the pump and the output capacitors usually leads to relatively high peak
input currents which can be much higher than the average load current. The regulator incorporates circuitry to
limit the input peak current, lowering the total EMI emission and lowering the output voltage ripple and the input
current ripple. The Input capacitor (CN) supplies most of the charge required by the input current peaks.
Efficiency
The efficiency of the charge pump regulator varies with the output voltage version, the applied input voltage, the
load current, and the internal operation mode of the device.
