WebApr 11, 2024 · The LDO also provides a high-power supply rejection ratio (PSRR) of 70 dB at 1 kHz, making it optimized for noise-sensitive functions. It also offers a fast line/load transient response against rapid changes to the input voltage or load current, said the company. The AP7387Q LDOs are AEC-Q100 Grade 1 qualified. WebJul 25, 2024 · Figure 1: A low-dropout regulator (LDO) using a feed-forward capacitor Much like the noise-reduction capacitor (C NR/SS ), adding a feed-forward capacitor has multiple effects. These effects include improved noise, stability, load response and the power-supply rejection ratio (PSRR).

Furthermore, a device with low output voltage noise across a wide bandwidth is beneficial for today’s modern rails in which noise sensitivity is a key consideration.
WebSep 12, 2024 · That is, the PSRR 254 of the NMOS LDO 102, 104 with the source follower 234 is improved by about 10 dB over the PSRR of the NMOS LDO 102, 104 of FIG. 4 B . In some cases, a peak PSRR frequency of the NMOS LDO 102 , 104 may be increased by about 1.5 times due to the added source follower 234 of FIG. WebToshiba offers a wide choice of LDO regulators in packages ranging from general-purpose to ultra-compact that are suitable for high-performance requirements, such as low noise, high ripple compressibility (PSRR), high output current stability (load transient response), and low current consumption, which are particularly required for state-of-the-art analog circuits.
WebApr 9, 2024 · The PSRR is most important at the switching frequency of the upstream supply (since there is a voltage ripple at this frequency). Additionally, PSRR is important above this frequency because of the switching harmonics. If you’re looking for good PSRR, the TPS7A4501-SP LDO offers a PSRR of over 45 dB at 100 kHz.
