REGULATORS GENERAL CHARACTERISTICS
• Specifications are for an ambient temperature of -30 to +85 °C.
• Advised bypass capacitor is the Murata™ GRM155R60G225ME15 which comes in a 0402 case.
• In general, parametric performance specifications assume the use of low ESR X5R ceramic capacitors with 20% accuracy
• Regulators which require a minimum output capacitor ESR (those with external PNPs) can avoid an external resistor if ESR
• The output voltage tolerance specified for each of the linear regulators include process variation, temperature range, static
• The PSRR of the regulators is measured with the perturbed signal at the input of the regulator. The power management IC is
• In the Low Power mode the output performance is degraded. Only those parameters listed in the Low Power mode section
• Regulator performance is degraded in the extended input voltage range. This means that the supply still behaves as a
• Note that in some cases, the minimum operating range specifications may be conflicting due to numerous set point and biasing
• When a regulator gets disabled, the output will be pulled towards ground by an internal pull-down. The pull-down is also
• 32 kHz spur levels are specified for fully loaded conditions.
• Short-circuit protection (SCP) is included on certain LDOs (see the SCP section later in this chapter). Exceeding the SCP
• The power tree of a given application must be scrubbed for critical use cases to ensure consistency and robustness in the
TRANSIENT RESPONSE WAVEFORMS
response refers to the overshoot only, excluding the DC shift itself. The transient line response refers to the sum of both overshoot
and DC shift. This is also valid for the mode transition response.

and 15% temperature spread, for a worst case stack up of 35% from the nominal value. Use of other types with wider
temperature variation may require a larger room temperature nominal capacitance value to meet performance specs over
temperature. In addition, capacitor derating as a function of DC bias voltage requires special attention. Finally, minimum
bypass capacitor guidelines are provided for stability and transient performance. Larger values may be applied; performance
metrics may be altered and generally improved, but should be confirmed in system applications.
