Frequently Asked Questions
What input voltage range is supported by the AP2114HA-2.5TRG1, and how much dropout should designers budget for?
The AP2114HA-2.5TRG1 accepts input voltages from 2.5V to 6V with an absolute maximum of 6.5V. The nominal dropout voltage is 0.45V, rising to a maximum of 0.75V at full 1A load. This means a minimum input of approximately 3.25V is needed to maintain the regulated 2.5V output under worst-case dropout conditions, which is important when powering it from a single lithium-ion cell.
How does the enable pin on the AP2114HA-2.5TRG1 help in multi-rail embedded system power sequencing?
The enable pin on the AP2114HA-2.5TRG1 allows the host controller or PMIC to assert or deassert the 2.5V output independently of the input supply. This is critical in multi-rail designs where certain subsystems must power up in sequence to avoid latch-up or inrush overcurrent. Pulling the enable pin low shuts down the 1A LDO output while the 2.5V to 6V input remains live, conserving power in standby modes.
For what kind of analog or RF circuits is the low-noise characteristic of the AP2114HA-2.5TRG1 most beneficial?
Low-noise LDOs like the AP2114HA-2.5TRG1 are particularly beneficial for powering phase-locked loops (PLLs), voltage-controlled oscillators (VCOs), ADC reference lines, and RF front-end modules where power supply noise couples directly into signal quality. Maintaining a clean 2.5V rail with the AP2114HA-2.5TRG1's 1A capacity and minimal output ripple prevents spurs and reduces noise floor in frequency synthesizers and precision measurement systems operating from 2.5V to 6V input supplies.
