1A LOW DROPOUT POSITIVE REGULATOR
1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V AND ADJUSTABLE OUTPUTS
Description
ZLDO1117 is a low dropout positive adjustable or fixed-mode
regulator with 1A output current capability.
The ZLDO1117 has a 2% tolerance across the industrial temperature
range and is guaranteed to have lower than 1.2V dropout at full load
current making it ideal to provide well-regulated outputs of 1.2V to
5.0V with input supply voltages up to 18V.
The ZLDO1117 is ideally suited to provide well-regulated supplies for
low voltage IC applications such as high-speed bus termination and
low current 3.3V logic supply across the whole industrial temperature
range.

Pin Descriptions
Pin
Name
I/O
Pin
Number
Function
Adj (GND) I 1
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage (Ground only for
Fixed-Mode).
V
OUT
O 2
The output of the regulator. A minimum of 4.7µF capacitor (0.05Ω ≤ ESR ≤ 0.5Ω) must be connected
from this pin to ground to insure stability. For improved ac load response a larger output capacitor is
recommended.
V
IN
I 3
The input pin of regulator. Typically a large storage capacitor (0.05Ω ≤ ESR ≤ 0.5Ω) is connected from
this pin to ground to ensure that the input voltage does not sag below the minimum dropout voltage
during the load transient response. This pin must always be 1.3V higher than V
OUT
in order for the
device to regulate properly.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to
absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
transporting these devices

Notes: 5. ZLDO1117 contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature
exceeded. When activated, typically at 150°C, the regulator Output switches off and then back on as the die cools.
6. Test condition for SOT223: T
A
= +27°C, no air flow, device mounted on 2”X2” polyimide PCB, 2 oz copper, 5.6mmX5.6mm pad.
7. Test condition for TO252: T
A
= +27°C, no air flow, device mounted on 2”X2” polyimide PCB, 1 oz copper, 2cmX2cm pad.
8. Ensures correct operation without entering dropout. Device will continue to operate below this minimum input voltage under dropout conditions.

Notes: 9. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant
junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
10. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input
and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
