Description
The PT5500 is a new series of high perfor-
mance 3.0 Amp, 5-pin Integrated Switching
Regulators (ISRs). This ISR operates from
input voltages as low as 3.0V to provide a
lower voltage power source for the latest
low-voltage logic IC’s. Features include
output voltage adjustment, inhibit function,
and short circuit protection. Only one ex-
ternal capacitor is required for proper
operation.

Notes: (1) The PT5500 Series requires a 100F electrolytic or tantalum output capacitor for proper operation in all applications.
(2) The ISR will operate down to no load with reduced specifications.
(3) This is a typical value only. The switching frequency will vary with input voltage.
(4) For operation below 0°C, the output capacitor C2 must have stable characteristics. Use either a low ESR tantalum or Oscon capacitor.
(5) See SOA curves or consult factory for the appropriate derating.
