R= Heatsink Ready

T= Tuned model**

L= Low Profile (0.465" height – open frame only)

**T (Tuned Model) Option

Designed for higher di/dt and

∆I applications, the

transient response has been modified to take advantage

of the capacitance on the customer's PCB. This unit

requires a minimum load capacitance of 5600

µF with an

impedance magnitude of less than 0.005

Ω at 15kHz. It

offers a minimum 3X improvement in the peak response

compared to a standard unit.
