GENERAL DESCRIPTION
The SP6260 family is a series of CMOS positive
low noise voltage regulators capable of
delivering up to 200mA of continuous current.
Each of these devices consists of a voltage
reference, an error amplifier, a resistor
network for setting the output voltage, a
current limit circuit for current protection and
a chip enable circuit.
The SP6260 series feature high ripple
rejection, low dropout voltage, low noise, high
output voltage accuracy and low current
consumption which make them ideal for use in
various battery-powered and hand-held
devices.
The SP6260 series is offered in the following
fixed output voltage options: 1.2V, 1.5V, 1.8V,
2.5V, 2.8V, 3.0V, 3.2V and 3.3V.
The SP6260 family is available in standard
lead free, RoHS compliant 5-pin SOT-23
package.
