Overview
The AP2402A33KTTR-E1 is a dual positive low-dropout (LDO) voltage regulator manufactured by Diodes Incorporated using CMOS technology. It integrates two independent output channels, each providing a fixed 2.8V output with a minimum capability of 300mA per channel. The device features high output voltage accuracy of ±2%, extremely low noise of 30µVrms over the 10Hz to 100kHz bandwidth, and high power supply ripple rejection (PSRR). Designed for battery-powered applications, it offers low quiescent current consumption and includes built-in current limit protection and chip-enable functions with quick discharge capabilities.
Feature Summary
- Dual-channel architecture with independent control via chip-enable pins
- High precision regulation with ±2% output voltage accuracy
- Ultra-low noise performance suitable for sensitive RF circuits
- Integrated thermal and current protection mechanisms
Applications
- Mobile phones and cordless telephones
- Wireless communication equipment
- Portable gaming devices
- Cameras and video recorders
- Sub-board power supplies for telecom equipment
Procurement Notes
Verify the specific suffix 'KTTR' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and pin-out compatibility. Ensure the 2.8V/2.8V dual-output configuration matches the system requirements. Confirm RoHS compliance status as indicated in the latest product change notices before finalizing procurement orders.
Selection Notes
Select this component when dual isolated 2.8V rails are required from a single input source. It is suitable for designs prioritizing low noise and high accuracy over adjustable voltage flexibility. Consider the DFN-2x2-8 package constraints for PCB layout and thermal dissipation needs compared to SOT-23 alternatives.
Part Context
This part belongs to the AP2402 series of dual LDO regulators produced by BCD Semiconductor Manufacturing Limited, now under Diodes Incorporated. The series includes variants with different fixed output combinations such as 2.5V/1.8V and 2.8V/1.8V. The AP2402A33 specifically denotes the 2.8V/2.8V output version packaged in TSOT-23-6 or DFN formats.
Replacement Considerations
Direct substitutes within the same family include AP2402A21KTTR-E1 (2.5V/1.8V outputs) and AP2402A31KTTR-E1 (2.8V/1.8V outputs), provided the voltage levels match the application design.
