Ordered TI Parts

by Manimaran Kanesan

The ESP32-M1 PCB with Analog Devices low-dropout (LDO) voltage regulator design were received and built. The board was tested and the range was verified. The test shows similar results to TI LDO. This closes the TI part substitution with a new LDO design.

The latest TI stock shows the TI LDO available in approximately three months’ time, almost similar to Analog Devices LDO, but ultimately Bison Science has decided to use TI LDO. This part is now purchased and will be sent directly to the manufacturer once available.
