Overview
The AP7312-1533FM-7 is a dual fixed output voltage low dropout linear regulator manufactured by Diodes Incorporated. It provides two independent channels with output voltages of 1.5V and 3.3V, each capable of delivering up to 150mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 60µA. It utilizes a DFN2018-6 package and includes integrated protection mechanisms such as current limit, short circuit, and thermal shutdown.
Feature Summary
- Dual channel architecture with independent enable pins for individual control
- Low dropout performance ensuring stable regulation under varying load conditions
- Integrated protection against overcurrent, short circuits, and overheating
- Fast transient response capability suitable for dynamic power demands
Applications
- Cellular phones
- Smart phones and PDAs
- MP3/MP4 players
- Bluetooth headsets
- Low power applications
Procurement Notes
Verify the specific ordering suffix FM-7 corresponds to the DFN2018-6 package configuration. Confirm that the 1533 designation matches the required 1.5V and 3.3V output combination. Ensure compatibility with RoHS3 standards if environmental compliance is required for the target assembly process.
Selection Notes
Select this component when a dual rail supply is needed from a single input source in space-constrained designs. The DFN2018-6 package offers a compact footprint compared to SOT26 alternatives. Consider the 60µA quiescent current for battery-operated devices where standby power consumption is critical.
Part Context
This part belongs to the AP7312 family of dual 150mA low dropout regulators. The datasheet indicates it is not recommended for new designs, suggesting the AP7345D as a preferred alternative for future projects. The device is designed for portable electronics requiring efficient power management.
Replacement Considerations
The datasheet explicitly recommends using the AP7345D instead of the AP7312 for new designs. Verify pinout and electrical specifications before substituting with other dual LDOs from different manufacturers.
FAQ
What is the maximum input voltage for the AP7312-1533FM-7?
The recommended operating input voltage range is 2V to 6V, with an absolute maximum rating of 6.5V.
How are the two output channels controlled?
Each channel has a dedicated enable pin (EN1 and EN2). Setting the respective pin high turns on the channel, while pulling it low turns it off.
What type of output capacitors are required for stability?
The device is stable with low ESR ceramic output capacitors. A minimum value of 1µF with an ESR greater than or equal to 10mΩ is recommended.
