Features
■ ■ ■ ■ ■ ■
Very low dropout voltage (0.45V) Very low quiescent current (typ. 50 µA in OFF mode, 500 µA in ON mode) Output current up to 500 mA Logic-controlled electronic shutdown Output voltages of 1.5; 1.8; 2.5; 3.3; 4.7; 5; 6; 8; 8.5; 9; 12V Automotive Grade product: 1.8V, 2.5V, 3.3V, 5.0V, 8.0V, 8.5V VOUT in DPAK and PPAK packages Internal current and thermal limit Only 2.2 µF for stability Available in ± 1% (AB) or ± 2% (C) selection at 25°C Supply voltage rejection: 80db (typ.) Temperature range: -40 to 125 °C put a part of the board in standby, decreasing the total power consumption. In the three terminal configuration the device has the same electrical performance, but is fixed in the ON state. It requires only a 2.2 µF capacitor for stability allowing space and cost saving. The LFxx is available as Automotive Grade in DPAK and PPAK packages, for the options of output voltages whose commercial Part Numbers are shown in the Table 32 (order codes). These devices are qualified according to the specification AEC-Q100 of the Automotive market, in the temperature range -40 °C to 125 °C, and the statistical tests PAT, SYL, SBL are performed.

Description
The LFxxAB/LFxxC are very Low Drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK and PPAK package and in a wide range of output voltages. The very low drop voltage (0.45 V) and the very low quiescent current make them particularly suitable for low noise, low power applications and specially in battery powered systems. In the 5 pins configuration (PENTAWATT and PPAK) a Shutdown Logic Control function is available (pin 2, TTL compatible). This means that when the device is used as a local regulator, it is possible to Table 1. Device summary
