Switched Capacitor

Regulated Voltage Inverter

DESCRIPTIO

EATURE

Regulated Negative Voltage from a

Single Positive Supply

Can Provide Regulated –5V from a 3V Supply

REG Pin Indicates Output is in Regulation

Low Output Ripple: 5mV Typ

Supply Current: 600µA Typ

Shutdown Mode Drops Supply Current to 5µA

Up to 15mA Output Current

Adjustable or Fixed Output Voltages

Requires Only Three or Four External Capacitors

The LTC^®1261 is a switched-capacitor voltage inverter

designed to provide a regulated negative voltage from a

single positive supply. The LTC1261CS operates from a

single 3V to 8V supply and provides an adjustable output

voltage from –1.25V to –8V. An on-chip resistor string

allows the LTC1261CS to be configured for output volt-

ages of –3.5V, –4V, –4.5V or –5V with no external

components. The LTC1261CS8 is optimized for applica-

tions which use a 5V or higher supply or which require

low output voltages. It requires a single external 0.1µF

capacitorandprovidesadjustableandfixedoutputvoltage

options in 8-pin SO packages. The LTC1261CS requires

one or two external 0.1µF capacitors, depending on input

voltage. Both versions require additional external input

and output bypass capacitors. An optional compensation

capacitor at ADJ/COMP can be used to reduce the output

voltage ripple.

Single Supply Applications

Each version of the LTC1261 will supply up to 12mA

output current with guaranteed output regulation of 5%.

The LTC1261 includes an open-drain REG output which

pulls low when the output is within 5% of the set value.

Output ripple is typically as low as 5mV. Quiescent current

is typically 600µA when operating and 5µA in shutdown.

The LTC1261 is available in a 14-pin narrow body SO

package and an 8-pin SO package.
