I don't have any
typical app for this IC (SOT23-5)
pin 1(IN) to accu (or via some R for measurement voltage/current/power on INA219)
pin 3(EN) to IN via some R ina my case 4,7k
pin 2(GND) to ESP-05 GND
pin 5(OUT) to ESP-05 VCC3V3
pin 4(NR) NC
that's all - i2c devices connected directly to GND/VCC3V3 and SDA/SCL to ESP8266 URXD/UTXD
of course don't forget about some big capacitor close to ESP8266
