LT1999-10/LT1999-20/ LT1999-50 APPLICATIONS INFORMATION Shutdown Capability If SHDN (Pin 8) is driven to within 0.5V of GND, the LT1999 is placed into a low power shutdown state in which the part will draw about 3μA from the V pins (+IN ...
Page 17
APPLICATIONS INFORMATION The REF pin should be either driven by a low source im- pedance (<100Ω) or should be bypassed with at least 1nF to a low impedance, low noise, signal ground plane (see Figure 4). Larger bypass capacitors on ...
