BCD AP2218T-5.0 1a low dropout linear regulator Datasheet

Preliminary Datasheet
1A LOW DROPOUT LINEAR REGULATOR
AP2218
General Description
Features
The AP2218 is a low dropout linear regulator with a
typical dropout of 300mV at 1A output current.
·
·
Minimum Guaranteed Output Current: 1A
Dropout Voltage at IOUT=1A: 300mV
·
·
·
·
Output Accuracy: ± 1%
Low Ground Current
Internal Current Limit and Thermal Protection
Reversed-battery and Reversed-lead Insertion
Protection
Fast Transient Response
The AP2218 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection
against any combination of high current and ambient
temperature that would create excessive junction temperatures.
·
The AP2218 has 3.3V and 5.0V versions.
The AP2218 is available in the industry standard TO220F-4 package.
