Description

The PL78L08XM3 series of surface mount regul ators are easy-to-use devices suitable for multitude of applications that require a regulated supply of up to 100mA. These regulators feature internal current limiting and t hermal shutdown, making them remarkably rugged. No external components are required with the PL78L08XM3 devices in many applications. These devices offer a substantial performance advantage over the traditional zener diode resistor combination, as output impedance and quiescent current are substantially reduced. Features:

  • Wide Range Of Available, Fixed Output Voltages
  • Internal Short-Circuit Current Limiting
  • Internal Thermal Overload Protection
  • No External Components Required Absolute Maximum Ratings (Ta=25°C) Typical Application Schematic Diagram PL78L08 Vout Vin C1 C2 A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low poin t on the input ripple voltage. Note : C1 and C2 are required if regulator is located far from power supply filter and load, or oscillation may induced on the loop. 576 3.41K 3.89K 7.8K 2.84K 13K 5pF 2.23K GND 1.5K 1.9K 100 100 5.7K Vout Vin SOT-89
