Description

The L78 series of three-terminal positive regulators is available in TO-220,

TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it

useful in a wide range of applications.

These regulators can provide local on-card regulation, eliminating the distribution

problems associated with single point regulation. Each type embeds internal current

limiting, thermal shut-down and safe area protection, making it essentially

indestructible. If adequate heat sinking is provided, they can deliver over 1 A output

current. Although designed primarily as fixed voltage regulators, these devices can

be used with external components to obtain adjustable voltage and currents.

Features

• Output current up to 1.5 A

• Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 V

• Thermal overload protection

• Short circuit protection

• Output transition SOA protection

• 2 output voltage tolerance (A version)

• Guaranteed in extended temperature range (A version)

L7812CD2T-TR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L7812CD2T-TR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。
