LD59100 Ultralow Dropout Regulator

STMicroelectronics LD59100 Ultralow Dropout Regulator is designed for use in various environments and applications. The LD59100 features an N-MOS topology which allows reduction of the Rdson of the pass-element. This maintains a very low-dropout voltage even with very low input power supply voltage. The device features very high PSRR characteristics over a wide frequency band, rendering it suitable for use as a secondary regulator for noise-sensitive applications. The enable function can be used to further decrease the overall current consumption in shutdown mode. The LD59100 embeds protection features, like current limit, thermal shutdown and reverse output current protection.

Low Dropout (LDO) Regulators

STMicroelectronics Low Dropout (LDO) Linear Regulators are a cost-effective way to deliver a stable and regulated output voltage. The LDOs simplify designs with few external components. Low-dropout linear regulators (LDOs) provide the best cost-performance tradeoff.

Ultralow Dropout LDOs

STMicroelectronics Ultra Low Dropout LDOs are a wide range of low and medium power LDO regulators with ultralow dropout and fast transient response. These ultralow LDOs simplify the design of high-efficiency, cost-effective linear power management (from 50mA to 3A of continuous load current). This makes them ideal for DSPs, MCUs, and FPGAs.
