Linear Regulator, Low Noise optimized for sensitive application such as RF or PLL blocks
Key Benefits
- Low noise: high power Supply Rejection Ratio (PSRR): - 65 dB at F < 10 kHz
- Low intrinsic noise: 20 uVRMS at 10 Hz to 20 kHz
- Low Bill-of-Material: optimized in density for the best trade-off for the given output current and input voltage range
- Cost efficient solution compared to external Power Management.
- Compatible with both Tantalum and ceramic capacitors
- Behavioral models: ease integration in SoC and optimized Power Management Network (PMNet) by verifying mode transitions as well as noise propagation

Technical information
- Technology: TSMC 180 G
- Add-ons:
- Over-voltage protection module (OPM) required for 2.7 to 5.5 V and 1.9 to 4.4 V input voltage range. The OPM enables over-voltage operation (up to 5.5 V) while using standard process 3.3 V devices. Power-On-Reset and Brown-On-Reset circuit (POR-BOR) Temperature sensor Power ON indicator
