DESCRIPTION
The SP6260 series are positive voltage regulator ICs fabricated by CMOS process. Each of these ICs consists of a voltage reference,
an error amplifier, a resistor network for setting 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 devices. The SP6260 devices have 1.5V, 1.8V, 2.5V, 2.8V,
3.0V, 3.2V and 3.3V versions. The SP6260 is available in standard
Lead Free, RoHS Compliant
SOT-23-5 packaging.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifica-
tions do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a
function of the maximum junction temperature, T
J(max),
the junction-to-ambient thermal resistance,
JA,
and the ambient tem-
perature, T
A.
The maximum allowable power dissipation at any ambient temperature is calculated using: P

Exceeding the maximum allowable power dissipation will result in excessive die temperature.
