TDF8553J
4
× 50 Watt power amplier and multiple voltage regulator
I Voltage regulators
N I2C-bus control
N Good stability for any regulator with almost any output capacitor value
N Six voltage regulators (microcontroller, display, audio processor, tuner, bus,
mechanical digital and drive)
N Selectable output voltages for regulators 1, 4 and 5
N Low dropout voltage PNP output stages
N High supply voltage ripple rejection
N Low noise for all regulators
N Two power switches (antenna switch and amplier switch)
N Standby regulators 2 and 6 (microcontroller and bus supply) operational during
load dump and thermal shut-down
N Low standby quiescent current (only regulators 2 and 6 operational)
N Second supply pin for connecting optional external DC-to-DC converter to reduce
internal dissipation
N Backup functionality for regulator 2
I Protection
N If connection to the battery voltage is reversed, all regulator voltages will be zero
N Able to withstand output voltages up to 18 V (supply line may be short-circuited)
N Thermal protection to avoid thermal breakdown
N Load-dump protection
N Regulator outputs protected from DC short-circuit to ground or to supply voltage
N All regulators protected by foldback current limiting
N Power switches protected from loss-of-ground and surge conditions

Applications
I Boost amplier and voltage regulator for car radios and CD/MD players
