1 / 13 page Preliminary Datasheet 1.0A LOW DROPOUT LINEAR REGULATOR AZ1117E Mar. 2013 Rev 1. 0 BCD Semiconductor Manufacturing Limited 1 General Description The AZ1117E is a low dropout three-terminal regulator with 1.0A output current ability, and the dropout voltage is specified at typical 1.1V at 1.0A current load, decreasing at lower load currents. The AZ1117E has been optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown protection solutions. Its circuit includes a trimmed band gap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature. The AZ1117E is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V fixed output voltage versions and ADJ output voltage version. The fixed versions integrate the adjust resistors. The AZ1117E is available in the industry-standard TO-252-2 (3) and SOT-223 packages. Features • Provide ADJ version (VREF=1.25V) and fixed voltage 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V with accuracy ±1% (except 1.2V) • Current Limit: 1.3A (Typ.) • Dropout Voltage: 1.1V (Typ.) @IOUT=1A • Regulator Stable with Low ESR MLCC • Excellent Line Regulation: 0.001%/V (Typ.) @ IOUT=30mA • Excellent Load Regulation: 0.2%/A @IOUT=1A • Quiescent Current: 3.5mA • Low Output Noise • PSRR: 70dB • OTSD Protection • Operation Junction Temperature: -40°C to 125°C Applications • TVs and LCD Monitors • PC Peripherals: Notebooks, Motherboards • STB Figure 1.
