Description

The L78L series of three-terminal positive regulators employ internal current limiting

and thermal shutdown, making them essentially indestructible. If adequate heat-sink

is provided, they can deliver up to 100 mA output current. They are intended

as fixed voltage regulators in a wide range of applications including local or oncard 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. The L78L series used as Zener diode/resistor

combination replacement, offers e improvement 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 (A) or ± 8 (C) selection

L78L15ABZ-AP属于集成电路（IC） > 线性 + 开关稳压器。意法半导体（ST）集团制造生产的L78L15ABZ-AP稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
