1A ULTRA LOW DROPOUT LINEAR REGULATOR
AZ2940
General Description
Features
The AZ2940 is a low dropout three-terminal regulator
with a typical dropout of 280mV at 1A output current.
·
·
Minimum Guaranteed Output Current: 1A
Dropout Voltage at I
=1A: 280mV Typ.
OUT
(Except 1.2V and 1.8V Versions)
Output Accuracy: ± 1%
Low Ground Current
Internal Current Limit and Thermal Protection
Reversed-battery and Reversed-lead Insertion
Protection
The AZ2940 provides current limit and thermal shut-
down. On-chip thermal shutdown provides protection
against any combination of high current and ambient
temperature that would create excessive junction tem-
peratures.
·
·
·
·
The AZ2940 has 1.2V, 1.8V, 2.5V, 3.3V and 5.0V ver- · Fast Transient Response
sions.
The AZ2940 series is available in the industry standard
Applications
TO-220-3, TO-263-3, TO-252-2 (1), TO-252-2 (3) and
SOT-223 power packages. (Detailed information

Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value
which is measured at VOUT+1V applied to VIN. In application, VIN should be no less than 2.5V.

Note: CIN is required if regulator is located far from power supply filter and is recommended to be 0.47µF or greater. To main-
tain stability, COUT is recommended to be 2.2µF or greater. The ESR of this capacitor is critical, please see curve.
