The maximum continuous supply voltage is 26V. Note 2: Full Load current (IFL) is defined as 1.5A for the GM66150 series. Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with VOUT + 1V applied to VIN Note 4: VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse-testing procedures to minimize temperature rise. Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus the ground pin current. Note 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 7: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 200mA load pulse at VIN = 20V (a 4W pulse) for T = 10ms. Note 8: VREF VOUT (VIN -1V), 2.3V VIN 26V, 10mA < IL IFL, TJ TJ MAX. Note 9: Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier gain = VOUT / VREF = (R1 + R2)/ R2. For example, at a programmed output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95 mV x 5V/1.240 V = 384 mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed. Note 10: VEN 0.8V and VIN 26V, VOUT = 0.

Their GND + VOUT OUT IN + 350mV dropout voltage at full load makes them especially valuable in battery powered systems and as high efficiency noise filters in "post-regulator" applications.

A trade-off for the low dropout voltage is a varying base drive requirement. But, Gamma's PNP process reduces this drive requirement to merely 1% of the load current. The GM66150 series of regulators is fully protected from damage due to fault conditions. Current limiting is lator from these numbers and the device parameters from this formula: PD = IOUT (1.01VIN - VOUT) provided. This limiting is linear, and output current under overload conditions is constant. Thermal shutdown where the ground current is approximated by 1% of IOUT. disables the device when the die temperature exceeds the 125°C maximum safe operating temperature. Transient protection allows device (and load) survival even when the input voltage spikes between -20V and Then the heat sink thermal resistance is determined with this formula: TJ(MAX) - TA qSA = (qJC + qCS ) PD +60V.

The low dropout properties of Gamma PNP regulators allow very significant reductions in regulator power dissipation and the associated heat sink without compromising performance. When this technique is employed, a capacitor of at least 0.1µF is needed directly between the input and regulator ground. GM66150 SERIES 40V, the overvoltage sensor temporarily disables the 9 Capacitor Requirements The adjustable regulator versions, GM66152 and For stability and minimum output noise, a capacitor on the regulator output is necessary. The value of this capacitor is dependent upon the output current; lower cur- GM66153, allow programming the output voltage anywhere between 1.25V and the 26V maximum operating rating of the family. Two resistors are used. rents allow smaller capacitors.
