AMS2950/AMS2951

Note 8: The junction-to-ambient thermal resistance are as follows:180°C/W and 160°C/W for the TO-92 (N) package with 0.40 inch and 0.25 inch leads to the

printed circuit board (PCB) respectively, 105°C/W for the molded plastic DIP (P) and 160°C/W for the molded plastic SO-8 (S). The above thermal resistances

for the N, S and P packages apply when the package is soldered directly to the PCB.

Note 9: May exceed input supply voltage.

Note 10: When used in dual-supply systems where the output terminal sees loads returned to a negative supply, the output voltage should be diode-clamped to

ground.

Note 11: V_shutdown³ 2V, V_in£ 30V, V_out=0, Feedback pin tied to 5V_TAP

Note 12: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the total temperature range.

Note 13: 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 50mA load pulse at V_IN=30V (1.25W pulse) for T =10 ms.

Note 14: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects

are covered under the specification for thermal regulation.

Note 15: Line regulation for the AMS2951 is tested at 150°C for I_L= 1 mA. For I_L= 100 mA and T_J= 125°C, line regulation is guaranteed by design to 0.2%.

See typical performance characteristics for line regulation versus temperature and load current.

Note 16: All AMS2950 devices have the nominal output voltage coded as the last two digits of the part number. In the AMS2951 products, the 2.5V 3.0V and

3.3V versions are designated by the last two digits, but the 5V version is denoted with no code of the part number.
