Datasheet LDO Regulators with Watch-Dog Timer 500mA Output LDO Regulators with Voltage Detector and Watchdog Timer BD3020HFP-M BD3021HFP-M 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. Features  Integrated WDT Reset Circuit [BD3020HFP-M]: Adjustable Detection Voltage through Vs pin [BD3021HFP-M]: WDT Can be Switched ON / OFF by Using INH Pin  Low saturation voltage by using PMOS output transistor  VCC Max Voltage: 50 V  Integrated Over Current Protection and Thermal Shut Down  HRP7 package Key specification  Low Circuit Current:  Output Voltage:  Output Current:  High Output Voltage Accuracy:  Low ESR ceramic capacitor can be used as output capacitor 80 μA (Typ) 5.0 V (Typ) 500 mA ±2 % Package W (Typ) × D (Typ) × H (Max)  HRP7 9.395 mm × 10.540 mm × 2.005 mm Figure 1.
