LDOs with identical V IN –V OUT and I Load conditions. It’s also important to compare LDOs with identical output voltages, since PSRR is usually better at lower output voltages. One of the dominant internal sources of PSRR in an LDO is the bandgap reference. Any ripple that makes its

LDOs with input voltage higher than 6.5V can be used in applications with wider input voltage range up to 80V. Please note that the LDO power dissipation is (Vin-Vout) * I_load so a high (Vin – Vout) drop will quickly lead to high LDO dissipation at moderate load currents. Part Number
