描述
由其分销商提供的 STMicroelectronics L4931CZ50-AP 的描述。
L4931 Series 300 mA 5 V Fixed Output VLDO Regulator with Inhibit - TO-92
STMicroelectronics LDOVoltage regulator chip, 5 Voutput, 250mAmaximum output, single output, TO-92, Through-hole, 3needle
LDO, FIXED, 5V, 0.25A, -40 TO 125DEG C; Output Type: Fixed; Input Voltage Min: -; Input Voltage Max: 20V; Fixed Output Voltage Nom.: 5V; Adjustable Output Voltage Min: -; Adjustable Output Voltage Max: -; Output Current: 250mA;
The L4931 series are very Low Drop regulators available in TO-220, SO-8, DPAK, PPAK and TO92 packages and in a wide range of output voltages. The very Low Drop voltage (0.4V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems. In PPAK and SO-8 packages a Shutdown Logic Control function is available TTL compatible. This means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. It requires only a 2.2 uF capacitor for stability allowing space and cost saving.
