DESCRIPTION

The TDA8133 and the TDA8133D are monolithic dual positive voltage regulators designed to provide fixed precision output voltages of 5.1 V and 8.0 V for currents up to 750 mA.

An internal reset circuit generates a reset pulse when the voltage of Output 1 drops below the regulated voltage value.

Output 2 can be disabled via the TTL input.

Short-circuit and thermal protections are included in all versions.

TDA8133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TDA8133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。
