High-Current LDO Regulators Power DSP Applications

Targeting DSP applications, four families of low drop out (LDO) regulators are said to combine features such as high output current, low dropout voltage, and fast transient response in a small, thermally efficient surface mount package. The four families consist of the TPS751xx and TPS753xx, which can drive up to 1.5 A of output current, and the TPS752xx and TPS754xx, which can output up to 2 A.
Each family contains five devices with different output voltages, one adjustable from 1.5 to 5 V and four with fixed voltages of 1.5, 1.8, 2.5, or 3.3 V. The devices also include integrated options for power-on reset and power-good functions. Other features include dropout voltages of 160 mV at 1.5 A and 210 mV at 2 A. Fixed output devices are guaranteed to provide a maximum output voltage tolerance of 2% over line, load and temperature ranges. The LDO regulators are available in 20-pin PowerPAD packages and have a starting price of $2.36 each/1,000.
