Texas Instruments REG102NA-3.3/250

The REG102 is a family of low-noise, low-dropout linear regulators with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout voltage (only 150mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF.

Typical ground pin current is only 600µA (at IOUT = 250mA) and drops to 10nA when not enabled. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions.

The REG102 has very low output noise (typically 28µVrms for VOUT = 3.3V with CNR = 0.01µF), making it ideal for use in portable communications equipment. On-chip trimming results in high output voltage accuracy. Accuracy is maintained over temperature, line, and load variations. Key parameters are tested over the specified temperature range (–40°C to +85°C).

The REG102 is well protected—internal circuitry provides a current limit that protects the load from damage; furthermore, thermal protection circuitry keeps the chip from being damaged by excessive temperature. The REG102 is available in the SOT23-5, SOT223-5, and SO-8 packages.

的reg102是一个家庭的低噪声,低压差线性稳压器的低接地电流。新的拓扑结构提供了比以前的DMOS设计显著改善,包括低压差(仅150mv典型值在满负荷),和更好的瞬态性能。此外,没有输出电容是需要稳定,不像传统的低压降稳压器是难以弥补和需要昂贵的低ESR电容大于1µF.
典型的接地引脚电流仅为600µ一(在输出电流= 250Ma)下降到10nA时不启用。不同的调节器与PNP通过装置,静态电流保持相对恒定的负载变化和辍学条件下。
的reg102具有很低的输出噪声(通常为28µVRMS为VOUT =与CNR = 0.01µF 3.3V),使得它非常适合使用在便携式通信设备。芯片切边精度高输出电压精度。精度保持在温度,线路和负载变化。关键参数在指定的温度范围内进行测试(40°C到85°C)。
的reg102是很好的保护内部电路提供电流限制,防止损坏负载;此外,热保护电路使芯片温度过高被损坏的。的reg102可在SOT23 - 5,SOT223封装- 5,和SO - 8封装。
