STMicroelectronics | L78L12ABZ

The L78L12ABZ is a three terminal positive voltage regulator with an output voltage of 12 V and an output current up to 100 mA, with internal current limiting and thermal shutdown features, available in through hole TO-92-3 package.

These devices are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators.

When used as Zener diode/resistor combination replacement, these devices offer an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise.

Features:

• Output current up to 100 mA
• Output voltages of 3.3, 5, 6, 8, 9, 10, 12, 15, 18, 24 V
• Thermal overload protection
• Short-circuit protection
• No external components are required
• Available in either ± 4% (AC) or ± 8% (C) selection
