FFF CompatibilityUses the same 16-TQFN footprint and pin assignments except for pin 12, which is configured as a Power-OK (POK) status output rather than a Power-On Reset (POR).Identical physical package dimensions, mounting style (SMD), and thermal pad dimensions (5mm x 5mm, 16-TQFN).Shares the same electrical performance baseline (4A, low dropout, input voltage range) but the feedback supervisor timing differs because POK responds immediately to +/-10% regulation windows instead of asserting a 140ms POR delay.The footprint and 20-pin configuration are physically different and completely incompatible with the target's 16-pin assignment.Housed in a smaller 20-VQFN (3.5mm x 3.5mm) package instead of the target's 16-TQFN (5mm x 5mm) package.Meets the 4A continuous output current ceiling, supports adjustable output voltage starting from 0.8V, and includes a comparable supervisor signal.
AI Summary

MAX8557ETE+T by Analog Devices: Linear Voltage Regulator IC Positive Adjustable 1 Output 4A 16-TQFN (5x5).

This is a same-family sibling that shares the identical physical 16-pin TQFN package and pinout, with the only distinction being the status feature on pin 12. Since pin 12 operates as a POK (Power-OK) instead of a POR (Power-On Reset), the supervisor delay behavior must be accounted for in the system.

  • Drop-in package and footprint compatibility
  • Shares identical 4A output current capability
  • Same adjustable output voltage range (0.5V to 3.4V)
  • Pin 12 functions as a real-time Power-OK (POK) indicator instead of providing a 140ms Power-On Reset (POR) delay.

A high-performance alternative from Texas Instruments that easily supports the required 4A load current while offering ultra-low noise performance. It requires a complete PCB footprint redesign due to its smaller 20-pin package.

  • Wide input voltage range up to 6.5V
  • Extremely low output noise (4.4 uVRMS)
  • Excellent PSRR for noise-sensitive rails
  • Requires physical board layout redesign due to package change
  • Minimum output voltage starts at 0.8V instead of 0.5V

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
