/PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced two high-current, low-dropout (LDO)
linear voltage regulators
with excellent noise and power supply rejection ratio (PSRR) performance in very small, easy-to-use packages. The 250-mA LP5907 and 800-mA LP38798 LDOs feature less than 10-µVrms output noise over the 10-Hz to 100-kHz bandwidth, eliminating the need for expensive and bulky filtering in a wide range of high-performance applications.

250-mA LP5907 LDO
Designed to meet the requirements of RF and analog circuits in applications such as mobile handsets, tablets and WiFi devices, the LP5907 linear regulator provides ultra-low noise, high PSRR, low quiescent current and low line or load transient response figures. Using innovative design techniques, the LP5907 offers industry-leading noise performance without a bypass capacitor, and includes the ability for remote output capacitor placement. The device is designed to work with 1-µF input and output ceramic capacitors, and when used in conjunction with the award-winning
online design tool, the LP5907 speeds and simplifies the design process. Watch a video at
LP5907 key features and benefits
800-mA LP38798 LDO
- Output noise of less than 10-uVrms provides a clean supply for noise-sensitive applications.
- PSRR of 75 dB at 1 kHz keeps a noisy supply from reaching target application.
- Output voltage range between 1.2 V and 4.5 V in 25 mV steps enables a variety of designs.
- Very small 0.65-mm by 0.65-mm by 0.40-mm micro SMD package allows placement very close to target application.
The LP38798 is a high-performance linear regulator capable of supplying 800-mA of output current. Designed to meet the requirements of sensitive RF and analog circuitry in applications such as basestations, the LP38798 features a unique linear topology on an advanced CMOS process to deliver ultra-low output noise and high PSRR at switching power supply frequencies. The LP38798 is stable with both ceramic and tantalum output capacitors and requires a minimum output capacitance of just 1-µF for stability.
