EM6156 - 5V 120mA Automotive LDO Regulator

General Description

The EM6156 offers a high level of integration by combining voltage regulation, voltage monitoring and software monitoring using a watchdog.

A comparator monitors the voltage applied at the VIN input comparing it with an internal voltage reference VREF.

Key Features

  • -40°C to +125°C temperature range.
  • Highly accurate 5 V, 120 mA guaranteed output (actual maximum current depends on power dissipation).
  • Output voltage tolerance.

R EM MICROELECTRONIC - MARIN SA EM6156 5V 120mA Automotive LDO Regulator with Watchdog Description The EM6156 offers a high level of integration by combining voltage regulation, voltage monitoring and software monitoring using a watchdog. A comparator monitors the voltage applied at the VIN input comparing it with an internal voltage reference VREF. The power-on reset function is initialized after VIN reaches VREF and takes the reset output inactive after a delay TPOR. The reset output goes active low when the VIN voltage is less than VREF. The RESET output is guaranteed to be in a correct state for a regulated output voltage as low as 1.2V. The watchdog function monitors software cycle time and execution.
