One 0.8 A buck regulator
Two 300 mA LDOs
20-lead, 4 mm Ã— 4 mm LFCSP package
Initial regulator accuracy: Â±1%
Overcurrent and thermal protection
Soft start
Undervoltage lockout
Open drain processor reset with threshold monitoring
Â±1.5% threshold accuracy over the full temperate range
Guaranteed reset output valid to VCC = 1 V
Dual watchdog for secure systems
Watchdog 1 controls reset
Watchdog 2 controls reset and regulators power cycle
Buck key specifications
Current mode topology for excellent transient response
3 MHz operating frequency
Uses tiny multilayer inductors and capacitors
