Overview
The AP2402A33DNTR-E1 is a dual positive voltage regulator IC fabricated using CMOS process technology. It integrates two independent LDO channels, each providing a fixed output of 2.8V with a minimum output current capability of 300mA per channel. The device features high output voltage accuracy of ±2%, low quiescent current of 50µA typical per channel, and extremely low noise of 30µVrms over the 10Hz to 100kHz bandwidth. It operates within an ambient temperature range of -40°C to +85°C and utilizes a DFN-2x2-8 package.
Feature Summary
- Dual-channel architecture with independent chip-enable control for power management
- High supply voltage ripple rejection capability for stable operation
- Integrated current limit circuitry for output protection
- Compatible with low ESR ceramic capacitors
Applications
- Mobile Phones
- Wireless Communication Equipment
- Portable Games
- Cameras and Video Recorders
- Battery Powered Equipment
Procurement Notes
Verify the specific suffix DNTR against the manufacturer's official datasheet to confirm the package type (DFN-2x2-8) and tape-and-reel configuration. Ensure the A33 designation matches the required 2.8V/2.8V output combination. Confirm RoHS compliance status and lead-free specifications prior to procurement to meet environmental standards.
Selection Notes
Select this component when a compact dual-rail solution is required for battery-powered applications. The low standby current of 0.1µA makes it suitable for devices requiring extended battery life. Verify that the load requirements do not exceed the 300mA per channel limit and that the input voltage remains within the specified operating range for the desired dropout performance.
Part Context
This part belongs to the AP2402 series of dual 300mA LDO regulators manufactured by Diodes Incorporated (formerly BCD Semiconductor). The series includes variants with different output voltage combinations such as 2.5V/1.8V and 2.8V/1.8V. The AP2402A33DNTR-E1 specifically denotes the 2.8V/2.8V version in the DFN-2x2-8 package.
Replacement Considerations
Check for other AP2402 variants like AP2402A21KTR-E1 if 2.5V/1.8V outputs are acceptable. Verify pinout compatibility across SOT-23-6, TSOT-23-6, and DFN packages before substituting.
