* Output current rating may be limited by duty

cycle, ambient temperature, and heat sinking.

Under any set of conditions, do not exceed the

specified current rating or a junction temperature

of 150˚C.

† Fault conditions that produce excessive

junction temperature will activate the device’s

thermal shutdown circuitry. These conditions

can be tolerated but should be avoided.

integration and reliability in low-voltage, high-current, linear regulator

applications such as personal computers (PCs) and set-top boxes. Each

device incorporates a monolithic low-level reference and control circuit

with a high-current pnp transistor in a power multi-chip module

(PMCM™). Regulated output voltages of 1.8 V or 3.3 V are also

available.

output current to 1 A. Regulator accuracy of 2 % and excellent

temperature characteristics are provided. The logic-compatible

ENABLE input gives the designer complete control over power up,

power down, and standby or sleep.

surface-mount package (tape and reel) with enhanced power-dissipating

qualities. They are rated for continuous operation between -30 C and

+100 C.
