mjbots/power_dist
This repository contains hardware and firmware for the mjbots powerdist and mjpower-ss boards. Both provide pre-charge, over-current limiting and connector fanout.

The ZXTR2005Z is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Diodes Incorporated in a SOT-89-3 package with 3 pins. -40℃~+125℃@(Tj) 1 100V 260uA 38mA 4.5V~5.5V 45dB@(100Hz) Fixed Positive SOT-89-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-89-3, from KiCad's library), ready for a KiCad board. 7 are in stock at JLCPCB (part C2942361). 1 open-source board in 1 repository on GitHub use it.
