RRP51045 Low-dropout Linear Regulator (LDO) Evaluation Board
The RTKP51045DE0000BU evaluation board provides a simple platform to evaluate the 3.5×3.5mm 20-Ld QFN RRP51045 low-dropout linear regulator (LDO).
概览
描述
The RRP51045 is an ultra-low noise, high PSRR, low dropout regulator capable of sourcing up to 4A of load current with only 250mV dropout voltage. It operates from an input voltage of 1.1V for extremely low voltage applications to 6.5V.
The LDO output voltage can be programmed from 0.5V to 2.075V using voltage setting pins on the IC in 25mV steps, eliminating the need for traditional external feedback resistors and saving PCB space. External feedback resistors can still be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.5V to 5.1V.
特性
- Maximum dropout: 250mV at 4A with BIAS
- Output voltage accuracy: ±1%
- Ultra-low output noise: 7µVRMS
- Input voltage range:
- Without BIAS: 1.4V to 6.5V
- With BIAS: 1.1V to 6.5V
- Output voltage range:
- Using PCB layout and voltage set pins: 0.5V to 2.075V
- External FB resistors: 0.5V to 5.1V
- Using PCB layout and voltage set pins: 0.5V to 2.075V
