Product Details
AP7343D-28W5-7 — 2.8 V, 300 mA LDO
Diodes AP7343D fixed regulator with active-high enable and automatic output discharge.
Overview
AP7343D-28W5-7 is a fixed 2.8 V, 300 mA low-dropout regulator in the Diodes AP7343D family. The CMOS device provides active-high enable, low quiescent current and automatic output discharge in a five-terminal SOT25 package. Check input headroom and junction temperature at the intended load.
Key Advantages
No output-setting divider.
Compact point-of-load regulation.
Defined power sequencing through EN.
D variant actively discharges VOUT on disable.
Feature Summary
- Fixed 2.8 V output and 300 mA recommended output current.
- Recommended VIN 1.7–5.25 V with sufficient dropout headroom.
- Active-high EN; tie to VIN if control is unused.
- D variant includes automatic output discharge.
- Typical circuit uses 1 µF input and output ceramic capacitors.
- SOT25 package; ambient operating range −40 °C to +85 °C.
Package & Footprint
LCDCHIP registers SC-74A, SOT-753. Diodes lists AP7343D-28W5-7 in SOT25, a five-terminal package. These descriptions refer to the same general five-lead outline; verify body dimensions, land pattern and pin-1 orientation against the manufacturer drawing before PCB layout. The package JPG is illustrative.
Pin Functions
Input supply; bypass close to VIN and GND.
Ground reference and bypass capacitor return.
Active-high enable; tie to VIN if enable control is not used.
No internal connection; follow manufacturer PCB guidance.
Regulated fixed output; place a ceramic capacitor close to VOUT and GND.
Pin numbers follow the Diodes SOT25 top-view drawing; do not transfer a DFN pin map to this W5 device.
Key Specifications
| Exact orderable | AP7343D-28W5-7 |
|---|---|
| Manufacturer | Diodes Incorporated |
| Nominal output voltage | 2.8 V fixed |

Output accuracy, dropout and transient behavior depend on operating conditions. Confirm the manufacturer tables for the selected output voltage, load and temperature.
Replacement Considerations
No internal alternative is linked because an exact LCDCHIP substitute was not confirmed through the product API. Match 2.8 V fixed output, five-pin SOT25 footprint and pinout, enable thresholds, capacitor stability, 300 mA capability and automatic output discharge before replacement.
Manufacturer Information
Diodes AP7343 data sheet DS37952 lists AP7343D-28W5-7 as a SOT25 orderable with identification code 6J. The ordering guide distinguishes the D output-discharge version from the non-D version. Consult the manufacturer data sheet for final electrical and package limits.
Applications
Fixed local supply.
Enable-controlled power rail.
Low-noise supply under stated conditions.
Compact point-of-load regulation.
Quality & Authenticity
Check exact order code AP7343D-28W5-7, identification code 6J, lot traceability, SOT25 body and pin-1 orientation against Diodes documentation. The generic JPG does not identify the device marking.
FAQ
Is this output adjustable?
No. AP7343D-28W5-7 has a fixed 2.8 V nominal output.
Does it automatically discharge VOUT when disabled?
Yes, this AP7343D orderable includes output discharge.
Can EN be left floating?
No. Drive EN to a defined high or low level; tie to VIN when enable control is not needed.
What is the SOT25 pinout?
Pin 1 VIN, 2 GND, 3 EN, 4 NC and 5 VOUT in the manufacturer top-view drawing.
Engineering Notice
Keep VIN and VOUT bypass capacitors close to the device and ground; the manufacturer typical circuit uses 1 µF on each rail and recommends at least 0.47 µF ceramic CIN. Account for ceramic DC-bias derating. Drive EN to a valid level and calculate dropout and junction temperature at full load.
