Description:Power Management IC Development Tools Radiation-hardened, QMLV and QMLP, 1.5A ultra-low-noise high-PSRR low-dropout (LDO) regulator 14-CFP 25 to 25
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for low-dropout regulator (LDO) layout, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce noise and parasitic inductance.
The output voltage tolerance of the TPS7H1111HBL/EM is specified as ±1.5% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage. For example, for a 1.1V output voltage, the tolerance would be ±16.5mV (1.1V x 1.5%).
The absolute maximum input voltage rating for the TPS7H1111HBL/EM is 13.2V. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 12V to ensure optimal performance and reliability.
The TPS7H1111HBL/EM is rated for operation up to 125°C junction temperature. However, the device's performance and reliability may degrade at high temperatures. It's recommended to follow the thermal design guidelines in the datasheet and to derate the device's performance accordingly.
To ensure stability, follow the recommended output capacitor selection guidelines in the datasheet, and use a capacitor with a low equivalent series resistance (ESR). Additionally, ensure that the input capacitor is properly sized and placed close to the device. Avoid using capacitors with high ESR or inductance, as they can cause oscillation.
