30 Aug 1999 972views Read Abstract
Description
Dual SOT-23 LDO test and evaluation board with on-board transient-load generator that can implement both line and load transients. Optional user-installed dual SOT-23 socket allows quick comparison of various LDOs.
Gerber File: P125D.zip (1967 kb)
Features
- Load-pulse generator with user-selectable frequency and duty-cycle and adjustable rise-time for:
- Line transient testing
- Load transient testing
- On-board dropout voltage sensing amplifier with 10x gain.
- User-selectable minimum/maximum load.
- Specifications: (All specifications subject to LDO specs)
- Vin max = 15V
- Io max = 2A (power-limited to 1W)
- Generator duty cycle = 0 - 100%
- Generator frequency range (recommended) = 100 Hz - 10 kHz
- Line transient range = ~3% - 10% Vin
- 10X Sensing amplifier input range = 0 - 1V
- 10X Sensing amplifier accuracy < 2%
