I’ve been working on an ESP32 module. Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that. This is a battery-ready module with a proper lithium battery charge circuit, lithium battery protection circuit, power supply, […]

Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The […]
