General Description
BD3020HFP-M BD3021HFP-M is a regulator IC with
integrated WDT (Watch Dog Timer), high output voltage
accuracy ±2.0 % and 80 µA (Typ) low circuit current
consumption. These are supports usage of low ESR ceramic
capacitor for output stability. The reset detection voltage can
be adjusted by connecting resistors on the Vs terminal
(BD3020HFP-M). They can be a stable power supply for any
applications while detecting malfunction of microcontrollers.
