AX6639/A
3A High Output Current LDO Regulator
GENERAL DESCRIPTION
The AX6639/A is a low noise, high output current, low quiescent current and low
dropout linear regulator. The Device includes pass element, error amplifier, band-gap,
current-limit and thermal shutdown circuitry. The output current is up to 3A. The
characteristics of low dropout voltage and less quiescent current make it good for some
critical current application, for example, some battery powered devices. The typical
quiescent current is approximately 200µA. There are 1.5V, 1.8V, 2.5V, 3.3V fixed output
voltage and adjustable output versions (SOP-8L-EP and TO263-5L Only). Built-in
current-limit, Short current protection and thermal-shutdown functions prevent any fault
condition from IC damage.
FEATURES
- Input voltage range : 2.6V~5.5V
- Adjustable Output (SOP-8L-EP and TO263-5L Only) and fixed Output voltage for 1.5V,
1.8V, 2.5V and 3.3V
- Dropout voltage is 380mV at 3A output current
- Guaranteed 3A output current
- Low quiescent current is 200µA (typ.)
- Fast transient response
- Current limit and thermal shutdown protection
- Short circuit current fold-back
- Available in the 3-Pin TO220, SOT-223, TO252, 2-pin TO263 and 5-Pin TO263 and
SOP-8L-EP Pb-Free packages
